Description

Technical Field

[0001] This application relates to the field of plate-shaped component inspection technology, and in particular to a plate-shaped component inspection device. Background Technology

[0002] Plate-shaped components refer to workpieces with a planar shape, widely used in mold manufacturing and machining. Heat sinks, as a type of plate-shaped component, are commonly used in the computer industry, and their performance directly affects the computer's operational stability and lifespan. To ensure that the heat sink provides good heat dissipation for the central processing unit, high precision requirements are placed on the flatness of the heat sink, the location of the mounting holes, and the diameter of the mounting holes.

[0003] Existing plate-shaped component inspection equipment can typically only inspect one of the following features: the flatness of the heat sink, the location of the mounting holes on the heat sink, and the diameter of the mounting holes.

[0004] The existing technical solutions mentioned above have the following drawbacks: existing plate-shaped component inspection equipment cannot continuously inspect multiple features of plate-shaped components, resulting in low inspection efficiency. Summary of the Invention

[0005] To improve testing efficiency, this application provides a plate-shaped component testing device.

[0006] This application provides a plate-shaped component inspection device, which adopts the following technical solution: A plate-shaped component inspection device, comprising: Storage tray, used to store plate-shaped parts to be tested; The feed tray is used to support the plate-shaped part to be tested and can make linear reciprocating motion; The first transfer mechanism is capable of transferring the plate-shaped part to be tested from the storage tray to the feed tray; A go-between testing organization is used to test the lower limit of the diameter of mounting holes on a plate-shaped component. A gauge testing organization is used to test the upper limit of the diameter of mounting holes on a plate-shaped component. A flatness testing mechanism is used to test the flatness of a plate-shaped component and to detect the position of mounting holes on the plate-shaped component. The second transfer mechanism can transfer the plate-shaped part to be tested on the feed tray to the go gauge inspection mechanism, and can transfer the plate-shaped part to be tested on the go gauge inspection mechanism to the no-go gauge inspection mechanism, and can also transfer the plate-shaped part to be tested on the no-go gauge inspection mechanism to the flatness inspection mechanism.

[0007] By adopting the above technical solution, the first transfer mechanism transfers the plate-shaped component to be tested from the storage tray to the feeding tray. Then, the feeding tray moves the plate-shaped component to be tested. Next, the second transfer mechanism transfers the plate-shaped component to be tested from the feeding tray to the go gauge inspection mechanism, which checks the lower limit of the diameter of the mounting holes on the plate-shaped component. Then, the second transfer mechanism transfers the plate-shaped component to be tested from the go gauge inspection mechanism to the no-go gauge inspection mechanism, which checks the upper limit of the diameter of the mounting holes on the plate-shaped component. Finally, the second transfer mechanism transfers the plate-shaped component to be tested from the no-go gauge inspection mechanism to the flatness inspection mechanism, which checks whether the flatness of the plate-shaped component and the position of the mounting holes on the plate-shaped component meet the standards. In this way, the flatness, the position of the mounting holes, and the diameter of the mounting holes of heat sinks or other plate-shaped components can be continuously inspected, improving inspection efficiency.

[0008] This application further specifies that: the go-regulation testing organization includes: The first bearing seat has a first limiting post and a first clearance hole; the first limiting post is used to limit the plate-shaped part to be tested; The first positioning detection sensor is located on one side of the first support base and is used to detect whether the plate-shaped component to be tested has arrived on the first support base; The first lifting seat is installed below the first bearing seat and can be moved up and down; The first driver is located below the first lifting seat, and its output end is connected to the first lifting seat to drive the first lifting seat to move up and down. The first displacement sensor is vertically mounted on the first lifting platform and can move up and down with the first lifting platform; The go gauge can be mounted on the first lifting seat in a floating manner; the go gauge can move up and down with the first lifting seat so that the top of the go gauge passes through the first clearance hole and is inserted into or removed from the mounting hole on the plate-shaped part to be measured. The first elastic element has its bottom end connected to the detection head of the first displacement sensor and its top end connected to the bottom end of the go gauge.

[0009] By adopting the above technical solution, when the plate-shaped component to be tested is placed on the top surface of the first support, the edge of the plate-shaped component abuts against the side wall of the first limiting post to restrict its position. When the first positioning detection sensor detects that the plate-shaped component to be tested has reached the top surface of the first support, the first driver drives the first lifting seat to move upward. The rising first lifting seat drives the first displacement sensor, the gauge, and the first elastic element to move upward. The tip of the gauge passes through the first clearance hole and inserts into the mounting hole on the plate-shaped component to be tested. If the tip of the gauge can completely pass through the mounting hole on the plate-shaped component to be tested, the mounting hole is qualified. If the tip of the gauge cannot pass through the mounting hole on the plate-shaped component to be tested, the mounting hole is unqualified. The first elastic element acts as a buffer to prevent the gauge and the detection head of the first displacement sensor from being damaged by excessive instantaneous force.

[0010] This application further specifies that: the go-between testing organization also includes: The first pressure seat is movably installed above the first bearing seat; The second driver is located above the first pressure seat, and its output is connected to the first pressure seat to drive the first pressure seat to move up and down.

[0011] By adopting the above technical solution, when the first positioning detection sensor detects that the plate-shaped component under test has reached the top surface of the first support, the second actuator drives the first pressure seat to move downwards. The bottom end of the descending first pressure seat abuts against the top of the gauge. The first pressure seat can flatten the plate-shaped component under test, reducing the defect rate and the scrap rate of products.

[0012] This application further specifies that: the non-stop gauge testing organization includes: The second bearing seat has a second limiting post and a second clearance hole; the second limiting post is used to limit the plate-shaped part to be tested; The second positioning detection sensor is located on one side of the second support base and is used to detect whether the plate-shaped component to be tested has reached the second support base; The second lifting seat is installed below the second support seat and can be moved up and down. The third driver is located below the second lifting seat, and its output is connected to the second lifting seat to drive the second lifting seat to move up and down. The second displacement sensor is vertically mounted on the second lifting platform and can move up and down with the second lifting platform; The stop gauge is mounted on the second lifting seat and can float up and down; the stop gauge can move up and down with the second lifting seat. The second elastic element has its bottom end connected to the detection head of the second displacement sensor and its top end connected to the bottom end of the stop gauge.

[0013] By adopting the above technical solution, when the plate-shaped component to be tested is placed on the top surface of the second support, the edge of the plate-shaped component abuts against the side wall of the second limiting post to restrict its position. When the second positioning detection sensor detects that the plate-shaped component to be tested has reached the top surface of the second support, the third driver drives the second lifting seat to move upward. The rising second lifting seat drives the second displacement sensor, the stop gauge, and the second elastic element to move upward. Although the tip of the stop gauge can pass through the second clearance hole, it cannot be inserted into the mounting hole on the plate-shaped component to be tested. If the tip of the stop gauge cannot be inserted into the mounting hole on the plate-shaped component to be tested, the mounting hole is qualified. If the tip of the stop gauge can be inserted into the mounting hole on the plate-shaped component to be tested, the mounting hole is unqualified. The second elastic element acts as a buffer to prevent the detection heads of the stop gauge and the second displacement sensor from being damaged by excessive instantaneous force.

[0014] This application further specifies that: the gauge testing organization also includes: The second pressure seat is movably installed above the second support seat; The fourth driver is located above the second pressure seat, and its output is connected to the second pressure seat to drive the second pressure seat to move up and down.

[0015] By adopting the above technical solution, when the second positioning detection sensor detects that the plate-shaped component under test has reached the top surface of the second support, the fourth driver drives the second pressure seat to move downwards. The bottom end of the descending second pressure seat presses against the top end of the plate-shaped component under test. The second pressure seat can flatten the plate-shaped component under test, reducing the defect rate and the scrap rate of products.

[0016] This application further specifies that the flatness testing organization includes: The third bearing seat has a third limiting post, a positioning post, and a third clearance hole; the third limiting post is used to limit the plate-shaped component to be tested; the positioning post can be inserted into the mounting hole on the plate-shaped component to be tested; The push block is located on one side of the third bearing seat and can move linearly back and forth on the top surface of the third bearing seat. A clearance groove adapted to the third limiting post is formed at the bottom. The fifth driver is located on the side of the push block away from the third support, and its output end is connected to the push block to drive the push block to make linear reciprocating motion. The third positioning detection sensor is located on the other side of the third support base and is used to detect whether the push block is in position. The third lifting seat is installed below the third support seat and can be moved up and down. The sixth actuator is located below the third lifting platform, and its output is connected to the third lifting platform to drive the third lifting platform to move up and down. The ejector pin is mounted on the third lifting seat in a floating manner and can move up and down with the third lifting seat. When the ejector pin moves upward with the third lifting seat, its top end can pass through the third clearance hole and abut against the bottom surface of the plate-shaped part to be tested, so that the plate-shaped part to be tested can be separated from the top surface of the third support seat. The third elastic element is fixed at its bottom end to the third lifting seat and at its top end to the bottom end of the ejector pin.

[0017] By adopting the above technical solution, after the plate-shaped component to be tested is placed on the top surface of the third support, the fifth driver drives the push block to move towards the third positioning detection sensor. If the flatness of the plate-shaped component to be tested is not up to standard, the push block will be restricted from passing over it. If the opening position of the mounting hole on the plate-shaped component to be tested is not up to standard, the positioning pin can no longer be inserted into the mounting hole, causing the surface of the plate-shaped component to be tested to tilt, which will also restrict the push block from passing over it. When the flatness of the plate-shaped component to be tested is up to standard, and the opening position of the mounting hole on it is up to standard, the push block can pass smoothly over it, and the third positioning detection sensor will provide feedback that the push block has moved into position. After completing the flatness and mounting hole position detection, the sixth driver drives the third lifting seat to move upward, thereby moving the third elastic element and the ejector pin upward. The tip of the ejector pin can pass through the third clearance hole and abut against the bottom surface of the plate-shaped component to be tested, so that the plate-shaped component to be tested is removed from the top surface of the third support. This makes it easier for the plate-shaped component under test to detach from the top surface of the third support.

[0018] This application further specifies that the first transfer institution includes: Base; The first boom is swayably mounted on the base; The second actuator is swayably mounted on the first actuator; The first suction nozzle, installed on the second actuator arm, is capable of generating negative pressure.

[0019] By adopting the above technical solution and using the linkage between the first and second actuators, the first suction nozzle can move flexibly over a large area, improving the flexibility and efficiency of transferring the position of the plate-shaped part under test. Compared with the method of transferring materials using grippers, the method of transferring materials using a suction nozzle causes less damage to the material surface, is suitable for transferring fragile, precision, or ultra-thin materials, improves the position transfer efficiency, and is suitable for confined working spaces.

[0020] This application further specifies that the second transfer agency includes: The transmission arm is capable of reciprocating linear motion along its own axis and can move up and down. The linear module is located below the drive arm; The seventh driver is mounted on the slider of the linear module, and its output shaft is fixedly connected to the drive arm; The first support rod is mounted on the transmission arm at one end; The second suction nozzle, installed at the other end of the first support rod, is capable of generating negative pressure; The second support rod is mounted on the transmission arm at one end; The third suction nozzle, installed at the other end of the second support rod, can generate negative pressure; The third support rod is mounted on the transmission arm at one end; The fourth suction nozzle, installed at the other end of the third support rod, is capable of generating negative pressure; The fourth, third, and second suction nozzles are arranged in a triangular pattern.

[0021] By adopting the above technical solution, the position transfer efficiency and accuracy of the plate-shaped component under test are improved, thereby enhancing the detection efficiency and accuracy. Utilizing the three-point adsorption principle, the plate-shaped component under test can be more stably adsorbed onto the bottoms of the fourth, third, and second suction nozzles.

[0022] This application further includes: The position adjustment mechanism is located between the feed tray and the gauge inspection mechanism. It is used to detect whether the plate-shaped part to be tested has reached the position adjustment mechanism and to adjust the position of the plate-shaped part to be tested.

[0023] By adopting the above technical solution, the position adjustment mechanism is used to accurately adjust the position of the plate-shaped part to be tested, which helps to improve the testing efficiency, accuracy and precision.

[0024] This application further includes: There are multiple waste chutes; at least one waste chute is located between the position adjustment mechanism and the go gauge inspection mechanism, at least one waste chute is located between the go gauge inspection mechanism and the no-go gauge inspection mechanism, at least one waste chute is located between the no-go gauge inspection mechanism and the flatness inspection mechanism, and at least one waste chute is located on the side of the flatness inspection mechanism away from the no-go gauge inspection mechanism. Multiple waste storage boxes are provided, each corresponding to a waste chute, at the outlet of the waste chute. The eighth driver has a horizontally positioned axis and its output end is connected to the feed tray, which is used to drive the feed tray to perform linear reciprocating motion.

[0025] By adopting the above technical solution, the second transfer mechanism can transfer the non-conforming test plate-shaped parts from the top surface of the rotating seat of the position adjustment mechanism, the top surface of the first bearing seat of the go gauge inspection mechanism, the top surface of the second bearing seat of the no-go gauge inspection mechanism, and the top surface of the third bearing seat of the flatness inspection mechanism to the inlet of the waste chute. The non-conforming test plate-shaped parts slide along the waste chute into the waste storage box. In this way, non-conforming products can be screened out in a timely and effective manner.

[0026] In summary, the beneficial technical effects of this application are as follows: 1. The first transfer mechanism transfers the plate-shaped component to be tested from the storage tray to the feed tray. Then, the feed tray moves the plate-shaped component. Next, the second transfer mechanism transfers the plate-shaped component to be tested from the feed tray to the go gauge inspection mechanism, which checks the lower limit of the diameter of the mounting holes on the plate-shaped component. Then, the second transfer mechanism transfers the plate-shaped component to be tested from the go gauge inspection mechanism to the no-go gauge inspection mechanism, which checks the upper limit of the diameter of the mounting holes on the plate-shaped component. Finally, the second transfer mechanism transfers the plate-shaped component to be tested from the no-go gauge inspection mechanism to the flatness inspection mechanism, which checks whether the flatness of the plate-shaped component and the position of the mounting holes meet the standards. This allows for continuous inspection of the flatness, mounting hole position, and mounting hole diameter of heat sinks or other plate-shaped components, improving inspection efficiency.

[0027] 2. When the plate-shaped component to be tested is placed on the top surface of the first support, the edge of the plate-shaped component abuts against the side wall of the first limiting post to restrict its position. When the first positioning detection sensor detects that the plate-shaped component to be tested has reached the top surface of the first support, the first driver drives the first lifting seat to move upward. The rising first lifting seat moves the first displacement sensor, the gauge, and the first elastic element upward. The tip of the gauge passes through the first clearance hole and inserts into the mounting hole on the plate-shaped component to be tested. If the tip of the gauge can completely pass through the mounting hole on the plate-shaped component to be tested, the mounting hole is qualified. If the tip of the gauge cannot pass through the mounting hole on the plate-shaped component to be tested, the mounting hole is unqualified. The first elastic element acts as a buffer to prevent the gauge and the detection head of the first displacement sensor from being damaged by excessive instantaneous force.

[0028] 3. When the plate-shaped component to be tested is placed on the top surface of the second support, the edge of the plate-shaped component abuts against the side wall of the second limiting post to restrict its position. When the second positioning detection sensor detects that the plate-shaped component to be tested has reached the top surface of the second support, the third driver drives the second lifting seat to move upward. The rising second lifting seat drives the second displacement sensor, the stop gauge, and the second elastic element to move upward. Although the tip of the stop gauge can pass through the second clearance hole, it cannot be inserted into the mounting hole on the plate-shaped component to be tested. If the tip of the stop gauge cannot be inserted into the mounting hole on the plate-shaped component to be tested, the mounting hole is qualified. If the tip of the stop gauge can be inserted into the mounting hole on the plate-shaped component to be tested, the mounting hole is unqualified. The second elastic element acts as a buffer to prevent the detection heads of the stop gauge and the second displacement sensor from being damaged by excessive instantaneous force.

[0029] 4. After the plate-shaped component to be tested is placed on the top surface of the third support, the fifth actuator drives the push block to move towards the third positioning detection sensor. If the flatness of the plate-shaped component to be tested is not up to standard, the push block will be restricted from passing over it. If the position of the mounting hole on the plate-shaped component to be tested is not up to standard, the positioning pin will no longer be able to be inserted into the mounting hole, causing the surface of the plate-shaped component to be tested to tilt, which will also restrict the push block from passing over it. When the flatness of the plate-shaped component to be tested is up to standard, and the position of the mounting hole on it is up to standard, the push block can pass smoothly over it, and the third positioning detection sensor will provide feedback that the push block has moved into position. After the flatness and mounting hole position detection are completed, the sixth actuator drives the third lifting seat to move upward, thereby moving the third elastic element and the ejector pin upward. The tip of the ejector pin can pass through the third clearance hole and abut against the bottom surface of the plate-shaped component to be tested, so that the plate-shaped component to be tested is removed from the top surface of the third support. This makes it easier for the plate-shaped component under test to detach from the top surface of the third support.

[0030] 5. By adding a position adjustment mechanism, the position of the plate-shaped part to be tested can be precisely adjusted, which helps to improve the testing efficiency, accuracy and precision. Attached Figure Description

Plate-shaped component to be tested. Detailed Implementation

[0033] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0034] Reference Figure 1 , Figure 2 and Figure 3This application discloses a plate-shaped component inspection device, including a storage tray 110, a feeding tray 120, a first transfer mechanism 130, a go gauge inspection mechanism 140, a no-go gauge inspection mechanism 150, a flatness inspection mechanism 160, and a second transfer mechanism 170. The storage tray 110 stores the plate-shaped component 200 to be tested. The feeding tray 120 is disposed on one side of the storage tray 110. The feeding tray 120 supports the plate-shaped component 200 to be tested and is capable of linear reciprocating motion to transfer the plate-shaped component 200 to be tested. The first transfer mechanism 130 is disposed between the storage tray 110 and the feeding tray 120. The first transfer mechanism 130 can transfer the plate-shaped component 200 to be tested from the storage tray 110 to the feeding tray 120. The go gauge inspection mechanism 140 is disposed on the side of the feeding tray 120 away from the storage tray 110. The go gauge inspection mechanism 140 is used to inspect the lower limit of the diameter of the mounting holes on the plate-shaped component 200 to be tested. The no-go gauge inspection mechanism 150 is located on the side of the go gauge inspection mechanism 140 away from the feed tray 120. The no-go gauge inspection mechanism 150 is used to inspect the upper limit of the diameter of the mounting holes on the plate-shaped component 200 to be tested. The flatness inspection mechanism 160 is located on the side of the no-go gauge inspection mechanism 150 away from the go gauge inspection mechanism 140. The flatness inspection mechanism 160 is used to inspect the flatness of the plate-shaped component 200 to be tested and whether the opening position of the mounting holes on the plate-shaped component 200 meets the standards. The second transfer mechanism 170 is located on the same side as the feed tray 120, the go gauge inspection mechanism 140, the no-go gauge inspection mechanism 150, and the flatness inspection mechanism 160. The second transfer mechanism 170 can transfer the plate-shaped component 200 to be tested from the feed tray 120 to the go gauge inspection mechanism 140, and can also transfer the plate-shaped component 200 to be tested from the go gauge inspection mechanism 140 to the no-go gauge inspection mechanism 150, and further transfer the plate-shaped component 200 to be tested from the no-go gauge inspection mechanism 150 to the flatness inspection mechanism 160. First, the first transfer mechanism 130 transfers the plate-shaped component 200 to be tested from the storage tray 110 to the feed tray 120. Then, the feed tray 120 moves the plate-shaped component 200. Afterwards, the second transfer mechanism 170 transfers the plate-shaped component 200 to be tested from the feed tray 120 to the go gauge inspection mechanism 140, where the go gauge inspection mechanism 140 detects the lower limit of the diameter of the mounting holes on the plate-shaped component 200. Next, the second transfer mechanism 170 transfers the plate-shaped component 200 to be tested from the go gauge inspection mechanism 140 to the no-go gauge inspection mechanism 150, where the no-go gauge inspection mechanism 150 inspects the upper limit of the diameter of the mounting holes on the plate-shaped component 200. Then, the second transfer mechanism 170 transfers the plate-shaped component 200 to the flatness inspection mechanism 160, where the flatness inspection mechanism 160 inspects whether the flatness of the plate-shaped component 200 and the position of the mounting holes on it meet the standards. In this way, the flatness, the position of the mounting holes, and the diameter of the mounting holes of the heat sink or other plate-shaped components can be continuously inspected, improving inspection efficiency.

[0035] Preferably, a storage trough 111 for accommodating the plate-shaped component 200 to be tested is formed on the top surface of the storage tray 110 to improve the stability of the position of the plate-shaped component 200 to be tested.

[0036] Preferably, the plate-shaped component inspection equipment further includes a frame 180. The top of the frame 180 is equipped with a feed tray 120, a first transfer mechanism 130, a go gauge inspection mechanism 140, a no-go gauge inspection mechanism 150, a flatness inspection mechanism 160, and a second transfer mechanism 170.

[0037] Reference Figure 1 , Figure 3 and Figure 4In one embodiment, the go gauge detection mechanism 140 includes a first support 141, a first support seat 142, a first positioning detection sensor (not shown), a first lifting seat 143, a first driver 144, a first displacement sensor 145, a go gauge 146, a first elastic element 147, a first pressure seat 148, and a second driver 149. The bottom end of the first support 141 is fixedly connected to the top end of the frame 180. The first support seat 142 is fixed to the middle of the first support 141. A first limiting post 1421 and a first clearance hole are formed on the top surface of the first support seat 142. The first positioning detection sensor is disposed on one side of the first support seat 142 and fixedly connected to the middle of the first support 141, and is used to detect whether the plate-shaped part 200 to be tested has reached the top surface of the first support seat 142. The first lifting seat 143 is movably mounted below the first support seat 142. The first driver 144 is disposed below the first lifting seat 143, with its axis vertically aligned, and fixed to the top end of the frame 180. The output end of the first driver 144 is fixedly connected to the bottom end of the first lifting seat 143, and is used to drive the first lifting seat 143 to move up and down. The first displacement sensor 145 is vertically mounted on the bottom of the first lifting seat 143 and can move up and down with the first lifting seat 143. The go gauge 146 is vertically and floatingly mounted on the top of the first lifting seat 143. The go gauge 146 can move up and down with the first lifting seat 143 so that the top end of the go gauge 146 passes through the first clearance hole and is inserted into or removed from the mounting hole on the plate-shaped member 200 to be tested. The bottom end of the first elastic member 147 is fixedly connected to the detection head of the first displacement sensor 145, and the top end is fixedly connected to the bottom end of the go gauge 146. The first pressure seat 148 is vertically and movably mounted above the first support seat 142. The second driver 149 is disposed above the first pressure seat 148, with its axis vertically set, and is fixed to the top end of the first bracket 141. The output end of the second driver 149 is fixedly connected to the top end of the first pressure seat 148, and is used to drive the first pressure seat 148 to move up and down. When the plate-shaped component 200 to be tested is placed on the top surface of the first support 142, the edge of the plate-shaped component 200 abuts against the side wall of the first limiting post 1421 to limit the position of the plate-shaped component 200. When the first positioning detection sensor detects that the plate-shaped component 200 to be tested has reached the top surface of the first support 142, the first driver 144 drives the first lifting seat 143 to move upward, and the second driver 149 drives the first pressing seat 148 to move downward. The rising first lifting seat 143 drives the first displacement sensor 145, the go gauge 146, and the first elastic member 147 to move upward, and the top end of the go gauge 146 passes through the first clearance hole and inserts into the mounting hole on the plate-shaped component 200. The bottom end of the descending first pressing seat 148 abuts against the top end of the go gauge 146.It should be noted that, assuming the standard diameter of the mounting hole is 18mm and the thread tolerance is ±0.05mm, the diameter of the cross-section of the GO gauge 146 should be 18.025mm, that is, the diameter of a qualified mounting hole is greater than or equal to 18.025mm. If the tip of the GO gauge 146 can completely pass through the mounting hole on the plate-shaped part 200 to be tested, then the mounting hole is qualified. If the tip of the GO gauge 146 cannot pass through the mounting hole on the plate-shaped part 200 to be tested, then the mounting hole is unqualified. The first pressure seat 148 can flatten the plate-shaped part 200 to be tested, reducing the defect rate and the scrap rate of products. The first elastic element 147 acts as a buffer, preventing the GO gauge 146 and the detection head of the first displacement sensor 145 from being damaged by excessive instantaneous force.

[0038] Preferably, first guide posts 1481 are formed at the top of opposite ends of the first pressure seat 148. Correspondingly, a first guide hole is formed at the top of the first support 141 for the first guide post 1481 to pass through. The first guide post 1481 cooperates with the first guide hole to accurately guide the movement direction of the first pressure seat 148.

[0041] Preferably, the first position detection sensor is a laser displacement sensor, which adopts a non-contact measurement method and can accurately measure the position of the plate-shaped part 200 to be tested.

[0042] Preferably, the first actuator 144 and the second actuator 149 can be pneumatic cylinders or hydraulic cylinders, providing high control precision. Alternatively, the first actuator 144 and the second actuator 149 can be electric actuators, eliminating the need for a working medium and improving the cleanliness of the working environment.

[0043] Preferably, the first elastic element 147 is a spring.

[0044] Reference Figure 1 , Figure 3 and Figure 5In one embodiment, the stop gauge detection mechanism 150 includes a second bracket 151, a second support seat 152, a second positioning detection sensor (not shown), a second lifting seat 153, a third driver 154, a second displacement sensor 155, a stop gauge 156, a second elastic element 157, a second pressure seat 158, and a fourth driver 159. The bottom end of the second bracket 151 is fixedly connected to the top end of the frame 180. The second support seat 152 is fixed to the middle of the second bracket 151. A second limiting post 1521 and a second clearance hole are formed on the top surface of the second support seat 152. The second positioning detection sensor is disposed on one side of the second support seat 152 and fixedly connected to the middle of the second bracket 151, and is used to detect whether the plate-shaped piece 200 to be tested has reached the top surface of the second support seat 152. The second lifting seat 153 is movably mounted below the second support seat 152. The third driver 154 is disposed below the second lifting seat 153, with its axis vertically arranged, and fixed to the top end of the frame 180. The output of the third driver 154 is fixedly connected to the second lifting seat 153, and is used to drive the second lifting seat 153 to move up and down. The second displacement sensor 155 is vertically mounted on the bottom of the second lifting seat 153 and can move up and down with the second lifting seat 153. The stop gauge 156 is mounted on the top of the second lifting seat 153 and can move up and down with the second lifting seat 153. The bottom end of the second elastic member 157 is fixedly connected to the detection head of the second displacement sensor 155, and the top end is fixedly connected to the bottom end of the stop gauge 156. The second pressure seat 158 ​​is mounted above the second support seat 152 and can move up and down. The fourth driver 159 is disposed above the second pressure seat 158, with its axis vertically set, and is fixed to the top end of the second bracket 151. The output of the fourth driver 159 is fixedly connected to the top end of the second pressure seat 158 ​​and is used to drive the second pressure seat 158 ​​to move up and down. When the plate-shaped component 200 to be tested is placed on the top surface of the second support 152, the edge of the plate-shaped component 200 abuts against the side wall of the second limiting post 1521 to limit the position of the plate-shaped component 200. When the second positioning detection sensor detects that the plate-shaped component 200 to be tested has reached the top surface of the second support 152, the third driver 154 drives the second lifting seat 153 to move upward, and the fourth driver 159 drives the second pressing seat 158 ​​to move downward. The rising second lifting seat 153 drives the second displacement sensor 155, the stop gauge 156, and the second elastic member 157 to move upward. Although the top end of the stop gauge 156 can pass through the second clearance hole, it cannot be inserted into the mounting hole on the plate-shaped component 200. The bottom end of the descending second pressing seat 158 ​​presses against the top end of the plate-shaped component 200 to be tested. It should be noted that, assuming the standard diameter of the mounting hole is 18mm and the thread tolerance is ±0.05mm, the diameter of the cross section of the stop gauge 156 should be 18.155mm, that is, the diameter of a qualified mounting hole is less than 18.155mm.If the tip of the stop gauge 156 cannot be inserted into the mounting hole on the plate-shaped component 200 under test, then the mounting hole is qualified. If the tip of the stop gauge 156 can be inserted into the mounting hole on the plate-shaped component 200 under test, then the mounting hole is unqualified. The second pressure seat 158 ​​can flatten the plate-shaped component 200 under test, reducing the defect rate and decreasing the scrap rate. The second elastic element 157 acts as a buffer, preventing damage to the stop gauge 156 and the detection head of the second displacement sensor 155 due to excessive instantaneous force.

[0045] Preferably, second guide posts 1581 are formed at the top of opposite ends of the second pressure seat 158. Correspondingly, a second guide hole is formed at the top of the second support 151 for the second guide post 1581 to pass through. The second guide post 1581 cooperates with the second guide hole to accurately guide the movement direction of the second pressure seat 158.

[0046] Preferably, there are four or eight second limiting posts 1521, arranged in a rectangular shape, used to limit the four corners of the plate-shaped piece 200 to be tested.

[0047] Preferably, the number of the second clearance hole, the second displacement sensor 155, the stop gauge 156, and the second elastic element 157 is the same as the number of mounting holes on the plate-shaped member 200 to be tested.

[0048] Preferably, the second position detection sensor is a laser displacement sensor, which adopts a non-contact measurement method and can accurately measure the position of the plate-shaped part 200 under test.

[0049] Preferably, the third actuator 154 and the fourth actuator 159 can be pneumatic or hydraulic cylinders, providing high control precision. Alternatively, the third actuator 154 and the fourth actuator 159 can be electric actuators, eliminating the need for a working medium and improving the cleanliness of the working environment.

[0050] Preferably, the second elastic element 157 is a spring.

[0051] Reference Figure 1 , Figure 3 and Figure 6In one embodiment, the flatness detection mechanism 160 includes a third support 161, a third bearing seat 162, a push block 163, a fifth driver 164, a third positioning detection sensor 165, a third lifting seat 166, a sixth driver 167, a push pin 168, and a third elastic member 169. The bottom end of the third support 161 is fixedly connected to the top end of the frame 180. The third bearing seat 162 is fixed to the top end of the third support 161. A third limiting post 1621, a positioning post, and a third clearance hole are formed on the top surface of the third bearing seat 162. When the plate-shaped piece 200 to be tested is placed on the top surface of the third bearing seat 162, the positioning post can be inserted into the mounting hole on the plate-shaped piece 200 to be tested, and the edge of the plate-shaped piece 200 to be tested abuts against the side wall of the third limiting post 1621 to limit the position of the plate-shaped piece 200 to be tested. A push block 163 is disposed on one side of the third support 162 and can reciprocate linearly on the top surface of the third support 162. Its bottom has a clearance groove 1631 adapted to the third limiting post 1621. A fifth actuator 164 is disposed on the side of the push block 163 away from the third support 162 and is fixedly installed on the top of the third bracket 161. The output end of the fifth actuator 164 is fixedly connected to the push block 163 and is used to drive the push block 163 to reciprocate linearly. A third positioning detection sensor 165 is disposed on the other side of the third support 162 and is used to detect whether the push block 163 is in position. A third lifting seat 166 is movably mounted below the third support 162. A sixth actuator 167 is disposed below the third lifting seat 166, with its axis vertically aligned, and is fixed to the top of the frame 180. The output end of the sixth actuator 167 is fixedly connected to the bottom end of the third lifting seat 166 and is used to drive the third lifting seat 166 to move up and down. The ejector pin 168 is mounted on the top of the third lifting seat 166 and can move up and down with it. When the ejector pin 168 moves upward with the third lifting seat 166, its top end can pass through the third clearance hole and abut against the bottom surface of the plate-shaped component 200 to be tested, so that the plate-shaped component 200 is detached from the top surface of the third support seat 162. The bottom end of the third elastic member 169 is fixed to the third lifting seat 166, and its top end is fixedly connected to the bottom end of the ejector pin 168. After the plate-shaped component 200 is placed on the top surface of the third support seat 162, the fifth driver 164 drives the push block 163 to move toward the third positioning detection sensor 165. If the flatness of the plate-shaped component 200 is not up to standard, the push block 163 will be restricted from passing over the plate-shaped component 200. If the position of the mounting hole on the plate-shaped component 200 to be tested is not up to standard, the positioning post can no longer be inserted into the mounting hole, causing the surface of the plate-shaped component 200 to tilt, which will also restrict the push block 163 from passing over the plate-shaped component 200 to be tested.When the flatness of the plate-shaped component 200 under test meets the standard, and the opening position of the mounting holes on the plate-shaped component 200 meets the standard, the pusher 163 can smoothly pass over the plate-shaped component 200 under test, and the third positioning detection sensor 165 will provide feedback that the pusher 163 has moved into position. After completing the flatness and mounting hole position detection, the sixth driver 167 drives the third lifting seat 166 to move upward, thereby driving the third elastic member 169 and the ejector pin 168 to move upward. The tip of the ejector pin 168 can pass through the third clearance hole and abut against the bottom surface of the plate-shaped component 200 under test, so that the plate-shaped component 200 under test can be separated from the top surface of the third support seat 162. In this way, the plate-shaped component 200 under test is more easily separated from the top surface of the third support seat 162. Among them, the third elastic member 169 plays a buffering role to prevent damage to the ejector pin 168 and the plate-shaped component 200 under test.

[0052] Preferably, there are four or eight third limiting posts 1621, arranged in a rectangular shape, used to limit the four corners of the plate-shaped piece 200 to be tested.

[0053] Preferably, there are two positioning posts, which correspond one-to-one with the two mounting holes on the plate-shaped part 200 to be tested.

[0054] Preferably, there are four third clearance holes. Correspondingly, there are four ejector pins 168 and four third elastic elements 169.

[0055] Preferably, the fifth actuator 164 and the sixth actuator 167 can be pneumatic or hydraulic cylinders, providing high control precision. Alternatively, the fifth actuator 164 and the sixth actuator 167 can be electric actuators, eliminating the need for a working medium and improving the cleanliness of the working environment.

[0056] Preferably, the third position detection sensor 165 is a laser displacement sensor, which adopts a non-contact measurement method and can accurately measure the position of the push block 163.

[0057] Preferably, the third elastic element 169 is a spring.

[0058] Reference Figure 1In one embodiment, the first transfer mechanism 130 includes a base 131, a first actuating arm 132, a first drive motor (not shown), a second actuating arm 133, a second drive motor (not shown), and a first suction nozzle 134. The bottom end of the base 131 is fixedly connected to the top end of the frame 180. The first actuating arm 132 is swayably mounted on the top of the base 131. The first drive motor is mounted inside the base 131, and its output shaft is fixedly connected to one end of the first actuating arm 132 for driving the first actuating arm 132 to sway. The second actuating arm 133 is swayably mounted on the first actuating arm 132. The second drive motor is mounted inside the end of the first actuating arm 132 away from the base 131, and its output shaft is fixedly connected to one end of the second actuating arm 133 for driving the second actuating arm 133 to sway. The first suction nozzle 134 is mounted on the bottom of the second actuator arm 133 at the end away from the first actuator arm 132, and is connected to the negative pressure generation source through an air duct to generate negative pressure. When the first transfer mechanism 130 transfers the plate-shaped component 200 to be tested, firstly, the first drive motor drives the first actuator arm 132 to swing, thereby moving the second actuator arm 133 and the first suction nozzle 134. Next, the second drive motor drives the second actuator arm 133 to swing, thereby adjusting the position of the first suction nozzle 134. Then, the first suction nozzle 134 generates negative pressure, causing the plate-shaped component 200 to be tested on the storage tray 110 to adhere to the bottom of the first suction nozzle 134. Next, the swinging first actuator arm 132 and the second actuator arm 133 move the first suction nozzle 134 to above the feed tray 120. Then, the first suction nozzle 134 no longer generates negative pressure, thereby releasing the plate-shaped component 200 to be tested. The use of a linkage between the first actuator 132 and the second actuator 133 allows the first suction nozzle 134 to move flexibly over a larger area, improving the flexibility and efficiency of position transfer of the plate-shaped part 200 under test. Compared to using grippers, the suction nozzle method causes less damage to the material surface, making it suitable for transferring fragile, precision, or ultra-thin materials, improving position transfer efficiency, and suitable for confined working spaces.

[0059] Preferably, the first and second drive motors can be stepper motors, which are relatively inexpensive. Alternatively, the first and second drive motors can be servo motors, which offer higher control precision.

[0060] Reference Figure 1 , Figure 2 and Figure 7In one embodiment, the second transfer mechanism 170 includes a transmission arm 171, a linear module 172, a seventh actuator 173, a first support rod 174, a second suction nozzle 175, a second support rod 176, a third suction nozzle 177, a third support rod 178, and a fourth suction nozzle 179. The transmission arm 171 is capable of linear reciprocating motion along its own axis and can move up and down. The linear module 172 is disposed below the transmission arm 171 and fixed to the top surface of the frame 180. The axis of the seventh actuator 173 is vertically arranged and fixedly installed on the slider 1721 of the linear module 172, and its output shaft is fixedly connected to the middle of the bottom end face of the transmission arm 171. One end of the first support rod 174 is fixedly installed at the top end of the transmission arm 171. The second suction nozzle 175 is fixedly installed at the bottom end of the other end of the first support rod 174 and is connected to a negative pressure generation source through an air duct, enabling it to generate negative pressure. One end of the second support rod 176 is fixedly installed at the top end of the transmission arm 171. The third suction nozzle 177 is installed at the bottom end of the other end of the second support rod 176 and is connected to the negative pressure generation source through an air guide pipe, enabling it to generate negative pressure. One end of the third support rod 178 is fixedly installed at the top end of the transmission arm 171. The fourth suction nozzle 179 is fixedly installed at the bottom end of the other end of the third support rod 178 and is connected to the negative pressure generation source through an air guide pipe, enabling it to generate negative pressure. When the plate-shaped part 200 to be tested on the top surface of the feed tray 120 is transferred to the top surface of the first bearing seat 142 of the gauge inspection mechanism 140, the linear module 172 drives the seventh driver 173, transmission arm 171, first support rod 174, second suction nozzle 175, second support rod 176, third suction nozzle 177, third support rod 178 and fourth suction nozzle 179 to move through the slider 1721, so that the second suction nozzle 175, third suction nozzle 177 and fourth suction nozzle 179 are located directly above the plate-shaped part 200 to be tested on the top surface of the feed tray 120. Next, the seventh actuator 173 drives the transmission arm 171 downward, thereby moving the first support rod 174, the second suction nozzle 175, the second support rod 176, the third suction nozzle 177, the third support rod 178, and the fourth suction nozzle 179 downward. Then, the second suction nozzle 175, the third suction nozzle 177, and the fourth suction nozzle 179 generate negative pressure, causing the plate-shaped component 200 to be tested to adhere to the bottom of the second suction nozzle 175, the third suction nozzle 177, and the fourth suction nozzle 179. Next, the seventh actuator 173 drives the transmission arm 171 upward, thereby moving the first support rod 174, the second suction nozzle 175, the second support rod 176, the third suction nozzle 177, the third support rod 178, the fourth suction nozzle 179, and the plate-shaped component 200 to be tested upward.Then, the linear module 172 drives the seventh actuator 173, transmission arm 171, first support rod 174, second suction nozzle 175, second support rod 176, third suction nozzle 177, third support rod 178, fourth suction nozzle 179, and the plate-shaped component 200 under test via the slider 1721, so that the plate-shaped component 200 under test comes into contact with the first support seat 142 of the gauge inspection mechanism 140. Afterwards, the seventh actuator 173 drives the transmission arm 171 downwards, thereby moving the first support rod 174, second suction nozzle 175, second support rod 176, third suction nozzle 177, third support rod 178, fourth suction nozzle 179, and the plate-shaped component 200 under test downwards. When the plate-shaped component 200 under test presses against the top surface of the first support seat 142, the second suction nozzle 175, third suction nozzle 177, and fourth suction nozzle 179 no longer generate negative pressure, thus releasing the plate-shaped component 200 under test. This results in high efficiency and accuracy in the position transfer of the plate-shaped component 200 under test, thereby improving the detection efficiency and accuracy. Similarly, the plate-shaped component 200 under test can be transferred from the top surface of the first support seat 142 of the go gauge detection mechanism 140 to the top surface of the second support seat 152 of the no-go gauge detection mechanism 150, and the plate-shaped component 200 under test on the top surface of the second support seat 152 of the no-go gauge detection mechanism 150 can be transferred to the top surface of the third support seat 162 of the flatness detection mechanism 160.

[0061] Preferably, the fourth suction nozzle 179, the third suction nozzle 177, and the second suction nozzle 175 are arranged in a triangle. By utilizing the three-point adsorption principle, the plate-shaped part 200 to be tested can be more stably adsorbed to the bottom of the fourth suction nozzle 179, the third suction nozzle 177, and the second suction nozzle 175.

[0062] Preferably, the seventh actuator 173 can be a pneumatic cylinder or a hydraulic cylinder, providing high control precision. The seventh actuator 173 can also be an electric actuator, eliminating the need for a working medium and improving the cleanliness of the working environment.

[0063] Preferably, there are four first support rods 174, evenly distributed along the axial direction of the transmission arm 171. There are four second support rods 176, evenly distributed along the axial direction of the transmission arm 171. There are four third support rods 178, evenly distributed along the axial direction of the transmission arm 171. Correspondingly, there are four second suction nozzles 175, each corresponding to one of the four first support rods 174. There are four third suction nozzles 177, each corresponding to one of the four second support rods 176. There are four fourth suction nozzles 179, each corresponding to one of the four third support rods 178. This further improves the position transfer efficiency and detection efficiency.

[0064] Reference Figure 1 and Figure 8In one embodiment, the plate-shaped component inspection device further includes a position adjustment mechanism 190. The position adjustment mechanism 190 is disposed between the feed tray 120 and the gauge inspection mechanism 140, and is used to detect whether the plate-shaped component 200 to be tested has reached the position adjustment mechanism 190, and to precisely adjust the position of the plate-shaped component 200 to be tested, thereby improving inspection efficiency, accuracy, and precision. Specifically, the position adjustment mechanism 190 includes a fixed base 191, a movable base 192, four ninth actuators 193, a rotating base 194, two tenth actuators 196, and a fourth position detection sensor 197. The bottom end of the fixed base 191 is fixedly connected to the top end of the frame 180. The movable base 192 is movably mounted on the top surface of the fixed base 191 in a horizontal plane. The fixed ends of the four ninth actuators 193 are respectively hinged to the four corners of the fixed base 191, and the output ends are respectively hinged to the four corners of the movable base 192. A rotating base 194 is rotatably mounted on the top surface of a movable base 192 via a rotating shaft 195. The top surface of the rotating base 194 is used to support the plate-shaped component 200 to be tested. The fixed ends of the two tenth actuators 196 are respectively hinged to two adjacent corners of the movable base 192, and the driving ends are respectively hinged to the side wall of the rotating shaft 195. A fourth position detection sensor 197 is fixed on the top surface of the rotating base 194 and is used to detect whether the plate-shaped component 200 to be tested has reached the top surface of the rotating base 194. The included angle between the axes of the two tenth actuators 196 is 90°. Each ninth actuator 193 and each tenth actuator 196 is a driving cylinder. When the plate-shaped component 200 to be tested is placed on the top surface of the rotating base 194, the position of the plate-shaped component 200 to be tested can be finely adjusted laterally, longitudinally, or obliquely by means of the tenth actuator 196, and the end orientation of the plate-shaped component 200 to be tested can be finely adjusted by means of the ninth actuator 193. It should be noted that when the position of the plate-shaped component 200 under test is finely adjusted laterally, longitudinally, or obliquely, the piston rods of the two tenth actuators 196 are locked, the rotating seat 194 cannot rotate around its own axis, while the piston rods of the two ninth actuators 193 are floating, and the piston rods of the other two ninth actuators 193 are activated. When finely adjusting the end orientation of the plate-shaped component 200 under test, the piston rods of the two tenth actuators 196 are floating, the rotating seat 194 can rotate, and the piston rods of all four ninth actuators 193 are locked.

[0065] Preferably, a displacement sensor is installed on each of the ninth actuators 193 and each of the tenth actuators 196. Each displacement sensor detects the displacement of the corresponding actuator and sends the detection result to the controller, which then controls whether each of the ninth actuators 193 and each of the tenth actuators 196 operates, thereby improving the degree of automation and control accuracy. An angle rotary encoder is installed at the hinge between the fixed end of each ninth actuator 193 and the fixed base 191, and at the hinge between the fixed end of each tenth actuator 196 and the movable base 192. Each angle rotary encoder detects the rotation angle of the corresponding hinge point and sends the detection result to the controller, which then controls whether each of the ninth actuators 193 and each of the tenth actuators 196 operates, further improving the degree of automation and control accuracy.

[0066] Preferably, the plate-shaped component inspection equipment also includes a controller. The controller is fixed on the frame 180 and is electrically connected to the first position detection sensor, the first driver 144, the first displacement sensor 145, the second driver 149, the second position detection sensor, the third driver 154, the second displacement sensor 155, the fourth driver 159, the fifth driver 164, the third position detection sensor 165, the sixth driver 167, the first drive motor, the second drive motor, the seventh driver 173, the linear module 172, and the eighth driver 183, respectively, to control whether they are working, thereby improving the degree of automation.

[0067] In one embodiment, the plate-shaped component inspection device further includes multiple waste chutes (not shown in the figure), multiple waste storage boxes (not shown in the figure), a moving base 182, and an eighth actuator 183. At least one waste chute is inclinedly disposed between the position adjustment mechanism 190 and the go gauge inspection mechanism 140, at least one waste chute is inclinedly disposed between the go gauge inspection mechanism 140 and the no-go gauge inspection mechanism 150, at least one waste chute is inclinedly disposed between the no-go gauge inspection mechanism 150 and the flatness inspection mechanism 160, and at least one waste chute is inclinedly disposed on the side of the flatness inspection mechanism 160 away from the no-go gauge inspection mechanism 150. The multiple waste storage boxes are correspondingly disposed at the outlets of the multiple waste chutes, and are used to store waste. The second transfer mechanism 170 can be used to transfer the unqualified test plate-shaped pieces 200 from the top surface of the rotating seat 194 of the position adjustment mechanism 190, the top surface of the first bearing seat 142 of the go gauge detection mechanism 140, the top surface of the second bearing seat 152 of the no-go gauge detection mechanism 150, and the top surface of the third bearing seat 162 of the flatness detection mechanism 160 to the entrance of the waste chute. The unqualified test plate-shaped pieces 200 slide along the waste chute into the waste storage box. In this way, unqualified products can be screened out in a timely and effective manner. The top end of the moving seat 182 is fixedly connected to the bottom end of the feed tray 120 and can make linear reciprocating motion to drive the feed tray 120 to make linear reciprocating motion. The axis of the eighth drive 183 is set horizontally and fixedly installed on the top surface of the frame 180. The output end of the eighth driver 183 is fixedly connected to the movable seat 182 via a transmission rod 184, and is used to drive the movable seat 182 to perform linear reciprocating motion, thereby driving the feed tray 120 to perform linear reciprocating motion. In this way, the feed tray 120 can perform linear reciprocating motion between the storage tray 110 and the gauge detection mechanism 140, improving feeding efficiency and ensuring feeding accuracy.

[0068] Preferably, the eighth actuator 183 can be a pneumatic cylinder or a hydraulic cylinder, providing high control precision. The eighth actuator 183 can also be an electric actuator, eliminating the need for a working medium and improving the cleanliness of the working environment.

[0069] Preferably, a slide rail 181 is fixed to the top of the frame 180. Correspondingly, a groove matching the slide rail 181 is formed at the bottom of the movable seat 182. The groove cooperates with the slide rail 181, improving the smoothness of movement of the movable seat 182.

[0070] The implementation principle of this embodiment is as follows: First, the first transfer mechanism 130 transfers the plate-shaped component 200 to be tested from the storage tray 110 to the feeding tray 120. Then, the feeding tray 120 moves the plate-shaped component 200 towards the position detection mechanism. Next, the second transfer mechanism 170 transfers the plate-shaped component 200 to be tested from the feeding tray 120 to the position adjustment mechanism 190, where the position adjustment mechanism 190 precisely adjusts the position of the plate-shaped component 200. Afterward, the second transfer mechanism 170 transfers the plate-shaped component 200 to be tested from the position adjustment mechanism 190 to the go gauge detection mechanism 140, where the go gauge detection mechanism 140 detects the lower limit of the diameter of the mounting hole on the plate-shaped component 200. Next, the second transfer mechanism 170 transfers the plate-shaped component 200 to be tested from the go gauge detection mechanism 140 to the no-go gauge detection mechanism 150, where the no-go gauge detection mechanism 150 detects the upper limit of the diameter of the mounting hole on the plate-shaped component 200. Subsequently, the second transfer mechanism 170 transfers the plate-shaped component 200 to be tested from the stop gauge inspection mechanism 150 to the flatness inspection mechanism 160. The flatness inspection mechanism 160 then inspects the flatness of the plate-shaped component 200 and whether the opening position of the mounting holes on the plate-shaped component 200 meets the standards. In this way, the flatness of the plate-shaped component, the opening position of the mounting holes, and the diameter of the mounting holes can be continuously inspected, improving the inspection efficiency, inspection accuracy, and inspection precision.
